Interface Path

All Superinterfaces:

Iterable<Path.Segment>

@Immutable
public interface Path
extends Iterable<Path.Segment>

A Path is a directed sequence of relationships between two nodes. This generally represents a traversal or walk through a graph and maintains a direction separate from that of any relationships traversed. It is allowed to be of size 0, meaning there are no relationships in it. In this case, it contains only a single node which is both the start and the end of the path.

     Path routeToStockholm = ..;

     // Work with each segment of the path
     for( Segment segment : routeToStockholm )
     {

     }

Method Detail

start

Node start()

Returns:

the start node of this path

end

Node end()

Returns:

the end node of this path

length

int length()

Returns:

the number of segments in this path, which will be the same as the number of relationships

contains

boolean contains(Node node)

Parameters:

node - the node to check for

Returns:

true if the specified node is contained in this path

contains

boolean contains(Relationship relationship)

Parameters:

relationship - the relationship to check for

Returns:

true if the specified relationship is contained in this path

nodes

Iterable<Node> nodes()

Create an iterable over the nodes in this path, nodes will appear in the same order as they appear in the path.

Returns:

an Iterable of all nodes in this path

relationships

Iterable<Relationship> relationships()

Create an iterable over the relationships in this path. The relationships will appear in the same order as they appear in the path.

Returns:

an Iterable of all relationships in this path
